Transfer files between server and clients

Hi all
i use oracle forms 11g r2 webutil
i have some questions :
1- How i can choose picture from client side and save it on server ( in folder ) ?
2- How i can print the picture from client side?
Thanks

Hello,
For transfering files, configure the Webutil library, then use its AS_To_Client() and Client_To_AS() methods.

Data streaming between server and client does not complete

Using an ad-hoc app, data streaming between server
and client does not complete as it supposed to be.
The process runs well in solaris 5.8, however under 5.9
we have found the characters stream buffer length limitation
is around 900 to 950 characters (by default we are using 3072
characters).
Example:
- We are transfering HTML file, which will be displayed
in the App client, with buffer=3072, the HTML only displayed / transfered
as xxxxxxxx characters, but with buffer=900 the HTML is displayed properly,
in this case, the only problem that we have is the file transfer will
eventually longer than usual.
- There is another case, where we have to transfer information (data) as stream
to the client. A long data stream will not appear at all in the client.
Any ideas why the change between 5.8 and 5.9 woudl cause problems?
The current app-driver that we are using is compiled using Solaris 5.6,
if possible we would like to have use of a later version, which is compiled using Solaris 5.9, do you think this will probably solve our problem?
Thanks
Paul

Does this have anything to do with Java RMI? or with Java come to think of it?

Speed between server and client when using FML

Bandwidth between server and client

HI
What is the minimum bandwidth can be allocated between server and client?

Hi,
Your question has no standard answer. The minimum bandwidth is variable to each specific system. It depends on many other factors too.

[vmware] Best way to share files between host and client

Good afternoon!
I have successfully installed VMware server on my machine and set up a virtual machine, powering Windows XP for study issues (emulation via wine does not do the trick for me). The virtual machine runs fast and stable but does not meet my requirements unless I have two issues faced:
First:
How to access a USB pendrive monunted by the host system properly within the client?
Second:
What is the best way to share file system space between host and client? Should I set up a Samba share which is accessible for both host and client or is it save to grant my VM access to my physical hard disc as a whole (using it as a partition)?
Thanks for answers in advance, I have still quite a lot to learn, when it comes to VMs.
Regards,
~cg

Do not setup your VMware to be able to access your physical disk as a whole. This would have you mounting the filesystem twice, corrupting it in the process.
You /can/ setup VMware with Sharing Folders that lets you share your filesystem (either / or just /home or something else) and that is what I would recommend.
As for accessing the pen drive from both operating systems at once, I'd say use the same Sharing Folders method. I always share /mnt so that I can access my cdrom/USB/etc from the vmware OS.
The sharing folders is basically the same as a samba share, but uses vmware's own method (HGFS). Samba is more secure (if you are worried about your VMware OS breaking from it's shell and attacking your real filesystem, which is unlikely). You need the vmware tools installed to make use of it.

Time sync between server and client

Hi guys,
I have written a chess server and client. My next step is to implement a clock which will be used in timed games, however, I am not sure of the best solution. I can't think of a reliable method to keep the client's time in sync with the servers because the event latency varies between individual events and clients.
My first idea was to send a 'tick' event every second but I dont think this the best solution. I have seen many applet based clients which have timers, such as Yahoo chess.
I know this question is a little vague, I can give more detail if needed.
Thanks,
Alex

To prevent client-side cheating, the server should keep the
"official" clock. Every so often (perhaps when a move gets made?),
notify both clients of the official time. Clients count seconds from
that official time.
This is a suboptimal solution because it leaves clients vulnerable
to network lag. I can't think of any other solution that doesn't give
clients some responsibility for tracking time, though, and that's a
big security hole.
If you're willing to open that hole, have each client report back to
the server the elapsed local time from when they recieved the
last move to when they made their move. Then update the other
client's clock accordingly.

Windows Media Player no sound while playing a avi file in server and client connection using TCP/IP connection

Hello there
I have a problem with my windows media player while using server and client connection by using TCP/IP connection. So when I play a video using Windows Media Player in LabVIew there isn't any sound come out but when I'm playing a video by a Windows Media Player only the sound will come out. Can you help me solve this problem?
I also upload the vi as the reference.
The username for the client is ihsanhaikalz and the password is ganteng
Thanks

Hi ican,
I was looking at your VI's but I cannot seem to pinpoint exactly where you are using Windows Media Player. In order to more quickly assist you, could you please recreate this issue more concisely in a smaller set of VIs. Also, were you able to get sound when you did not use the TCP/IP connection and simply played the files in LabVIEW?
I noticed in a few places that you were using the Play Sound File.VI from the Graphics and Sounds palette. Is that what you are refering to? I noticed there that the file path that you have designated for the song is simply the song title. Instead, this should be a path to where the song is located on your computer.
Also, if you are planning on using Windows Media Player, have you considered using the ActiveX commands for Windows Media Player? Here are a few examples if you are unfamiliar with this functionality.
Example 1 and Example 2.
I hope this helps!

Transfer files between ASA and a host across a VPN

Hello Guys,
I have a Remote Access VPN between an ASA and a Windows PC, the issue that I'm seeing is that I can't transfer files between the ASA and my PC across the VPN.
The first time I thought that because the size of the file and some issue with my ADSL service bandwidth could be the problem. However, I tried to copy the running config of the ASA to my PC and is also impossible. I received this error:
ASA# copy running-config tftp:
Source filename [running-config]?
Address or name of remote host []? 10.10.10.2 ----> This is the address of my PC over the VPN tunnel
Destination filename [running-config]? ASA-Config04032014
Cryptochecksum: f5a9f8cb 9f63b2e5 e8c99e36 9498cb50
%Error writing tftp://10.10.10.2/ASA-Config04032014 (Timed out attempting to connect)
Does anybody had this kind of problem before?
Thanks in advance,

I was wondering if I transfer files between a PC and Mac via Ethernet cable can I reverse the transfer from a Mac to a Pc?
Yes. Start Windows File Sharing on the Mac and then access it on the PC.

Hi,
Trying to help :-
What roll ODI Server play in the entire ODI ArchiTechture?
ODI Server will act as a cenratilsed system for all your ODI clients
You can call this ODI server as an execution server for all your ODI clients .
When this is needed ?
(some real time examples to explain the need)
If there is team need to work on a cenratlised application ...
say MachineDev1 (developer1) , MachineDev2 (developer2) .. and MachnAnlayst1 (An1), MachnAnlayst2 (An2) need to work on an single application
The developer1 will create projects based upon his machine ,
The developer2 will create projects based upon his machine ,
and the analysts/operators will try to execute the application from their machines with their machine agents.
the application will reffer the paths for temperory/supporting files/folders on the agent machines which they are running ...
this will be a difficult task, if you dont have a similar folder sturcture in all of your machines ..
In order to avoid this conflict you need a centralised system for running your jobs from different machines
say SVR (from your example). put all the supporting files/folders in this system while developing projects each develpoer need to consider this server as an execution server.
so if any execution comes from any clients with this agent, it will reffer to the machine SVR folders and you can have a centralaised enviorment to work for different machines.

How can I transfer file between PC and iPhone?

iPhone does not show in MyComputer after connected to PC. How can I transfer file to/from PC?

iPhone does not support disk mode, so doesn't show in My Computer. You can transfer files through iTunes (Apps tab in the main window) if you have an app on the iPad that works with that kind of file. If you don't have an app, GoodReader is a good choice because it handles many different file types.
Alternatively, you could user Dropbox (cloud storage) which will allow you to share files on your PC with the iPad.
